"I got really, really drunk," she said during a roundtable interview with The Hollywood Reporter. "But then that led to more anxiety when I got home because I was like, 'What have I done? I don't know.' And he was married. And it was going to be my first time kissing a married man, and guilt is the worst feeling in your stomach. And I knew it was my job, but I couldn't tell my stomach that. So I called my mom, and I was like, 'Will you just tell me it's OK?' It was just very vulnerable.  And you don't know what's too much. You want to do it real, you want everything to be real, but then … That was the most vulnerable I've ever been."

The movie about travelers to a distant planet also stars Michael Sheen, Laurence Fishburne and Robert Larriviere. It's due out in December 2016.

J-Law of course stars in "Mockingjay part 2," which filmed largely in Atlanta and opens Friday.
